Beacon
Beacon frames
announce the existence of the wireless local area network and enable stations to establish
and maintain communications in an orderly fashion. A beacon frame carries the following information,
some of which is optional:
•
The
Timestamp
is used by stations to update their local clock, enabling synchronization among all
associated stations.
•
The
Beacon interval
defines the amount of time between transmitting beacon frames. Before entering
power save mode, a station needs the beacon interval to know when to wake up to receive the bea-
con.
•
The
Capability Information
lists requirements of stations that want to join the
WLAN
. For example, it
indicates that all stations must use
WEP
.
•
The
Service Set Identifier
(
SSID
).
•
The
Basic Rate Set
is a bitmap that lists the rates that the
WLAN
supports.
•
The optional
Parameter Sets
indicates features of the specific signaling methods in use (such as fre-
quency hopping spread spectrum, direct sequence spread spectrum, etc.).
•
The optional
Traffic Indication Map
(TIM) identifies stations, using power saving mode, that have data
frames queued for them.
Bridge
A connection between two local area networks (
LAN
s) using the same protocol, such as Ethernet or
IEEE
802.1x
.
Broadcast
A
Broadcast
sends the same message at the same time to everyone. In wireless networks, broadcast
usually refers to an interaction in which the access point sends data traffic in the form of
IEEE
802.1x
Frame
s to all client stations on the network.
Some wireless security modes distinguish between how unicast, multicast, and broadcast frames are
encrypted or whether they are encrypted.

and

BSS
A
basic service set
(BSS) is an
Infrastructure Mode
Wireless Networking Framework
with a single access
point. Also see extended service set (
ESS
) and independent basic service set (
IBSS
).
